METHOD or PRODUCING INTERLINING AND A FILLER THEREFOR. f t

PATENT OFFICE.

Application filed March 15,1926. serial No. 94,811.

The invention relates to an interlining and filler therefor, and amethod of producing the same, as described in the present specificationand illustrated in the accompanying drawings that form part of the same.

The invention consists essentially of the novel features of constructionpointed out in the claim for novelty following a description containingan explanation in detail of an acceptableform of the invention.

The objects of the invention are to facilitate the insulation of walls,roofs, and flooring and maintain the atmospheric conditions of anenclosure suitable for its uses, such as the interlinings in passengercars, freight cars, buildings, refrigerating plants and all chambersrequiring protection from external weather conditions and to do thiswithout interfering with a certain circulation of air as represented inthe constant transference of air in globules within the filler of thecomposite sheets, and thereby avoid inertia in the actual liningmaterial which is inherent in felts and pressed cloths, pulps and paperused as fillers; to eliminate the absorption and retention of moistureand hot or cold air; to produce a material at a low cost withoutreducing its efficiency or its usefulness; to insure great facility inthe installation of the insulation in vehicles and buildings; tomaintain even tempera tures for the occupants ofa'partments,compartments or other chambers; to apply this invention to many andvarious uses other than at present; and generally to provide a durableand reliable insulation, which will bring forth excellent results in allapplica-v tions and be economical with regard to its production.

In the drawings, Figure 1 is a cross sec tional view of the insulationshowing the filler and layers.

Figure 2 is a cross sectional view showing the hair on both sides of thebacking and binding sheet.

Figure 3 is a plan view of the backing and binding sheet showing thehairs or fibers locked therein.

Figure 4: is a diagrammatic view showing the means for interlocking thehair and backing to form the filler.

Figure 5 is a diagrammatic View showing the means for assembling thelayers.

Figure 6 is a fragmentary-plan view showing the use of gauze and felt asa binder sheet.

Like numerals of reference indicate corresponding parts in thevariousfigures.

Referring to the drawings, the numeral 7 indicates the filler in bothforms of the invention, which is made of loose hair and paper preferablycrepe paper 8, as shown in Figure 3 or felt paper 9 reinforced by atextile fabric lOas shown in Figure 6. In the crimped and crisped paper,commonly termed crepe paper in commerce, the expansion and contractiondue to atmospheric conditions is fully provided for and in thereinforced felt paper the same advantage is ained.

The filler 7 is shown in Figures 1, 3, 4 and 5, as having a bat of loosehairy material 11 on the one side only, while in Figure 2 the bats ofhair are shown on both sides of the crepe paper 8.

The bat is frequently made of animal hair, but it must be understoodthat there are many animal, vegetable and mineral fibers that may beused, and further there may be mixtures of the different fibres,according to the use that the filler is put to, the essential.

features being the comparative looseness of the bats to permit thecollection of air globules and the firm adherence of the bat or bats tothe ventilated binding sheet, not, withstandingthe unpressed conditionof the hair and its remoteness from the felt condition.

The method employed for securing and locking the hair bats to the paperis preferably by means of a loom having numerous needles with barbpoints indicated by the numeral 12, these points carrying strands of thehair through the paper to form the hair covering for the latter. Theneedles make innumerable holes in the aper, and in carrying the hairlengths with them interlock the hair and the paper, said needlesclearing themselves on their backward or withdrawal strokes as the barbsare in the shape of flaring points.

The method is the same for attaching the loose hair to the two sides ofthe paper as shown the only difference being that of an extra step inthe process.

The bat is prepared in any machine that will bring it togethersatisfactory, such as a heater or batter of conventional design and inthis the hairs are assembled and extended and formed into a bat anddelivered on a. large cylindrical roll.

The bat in this condition is quite loose and the hairs simply cling toone another by capillary attraction and it is not pressed or felted. Inthis condition it is passed into the machine 15, where it is punched bythe barb points into the accompanying sheet of ,paper adapted to form apermanent binder.

The binding sheet andthe hair come out of the machine together andconstitute the filler in any interlining required.

For wall interlining this filler is fed into the machine 16 with sheetsof asbestos l7 and 18 and the insert paper sheets 19 and 20 from rollsconveniently spaced, as well as the gauze outer layers 24 and 25, thegauze 24 covering the asbestos paper 17 over the paper binding sheet andthe gauze 25 covering the asbestos sheet 18 on the insert sheet andplain paper 20.

The composite sheet formed of the hair filler, the asbestos paper theplain paper and the gauze is cross stitched in the machine 26, whichsecurely sews the outer gauze covering and the layers together, therebyproviding a reliable sheet of interlining that can be rolled and shapedand installed with great facility.

In using this invention, take for example the interlining of passengercars on rail ways, the sheets are secured in the wall of the car,between the outside sheeting and the inside sheeting, thereby insuringan effectual bar to the penetration of moisture or hot or cold air andwhile it has been known for many years to insert an interlining sheetbetween sheetings of Walls, ceilings, floors and other places, it is notknown so far as I am aware to construct and furnish an insulation havingfeatures such as are described herein, and pointed out in the claim.

The adherence of comparatively loose hair to burlap by the method ofinserting picks through the hair and burlap is already well known inthis particular art, in fact it has been in use for some years, there,fore to push the ends of hair throughthe woven material is not novel,but to push loose strands of hair through and coincidently ventilate abinding sheet of paper constitutes a novel idea and brings forth a newarticle as the punching by the barb points opens up the paper as well asinterlocks the hair so that there are two purposes accomplished in thismethod, one of which is the formation and the aeration of the filler theother.

Further it may be said that the crimping and crisping of the paper,forming the binding sheet, produces a backing for the loose hair thatmeets all the conditions of insulation and particularly those regardingmoisture and heat. It must be thoroughly understood that this inventionis unique in the fact that it comes out of an art that has been fairlywell taken up in earlier inventions and yet its essential featurescreate an entirely new article, as well as provide efficiency in wall,floor and ceiling insulation.

What I claim is A step in a method of making an inter-' lining fillercomprising the flattening of a tangle of loose hairs, and laymg of thehairs on a stiff sheet of crepe paper having flattened crinkles, andpunching many irregular holes through the paper for ventilationpurposes, and carrying strands of hair CHARLES HANSON RAYNER.
